Site and type of craniopharyngiomas impact differently on 24-hour circadian rhythms and surgical outcome. A neurophysiological evaluation

Abstract

This study aimed to quantify 24. h body core temperature (BcT°) and sleep-wake cycle rhythm alterations in craniopharyngioma (CP) patients and to identify markers related to the postsurgical outcomes. Ten consecutive CP patients underwent neuroradiological, endocrinological and ophthalmological evaluations, 24. h BcT° and sleep-wake cycle recordings before and after endoscopic endonasal surgery. The sample included four women and six men. Nocturnal sleep efficiency was pathologically reduced in eight patients before surgery. Seven out of ten patients presented one to three daytime naps. 24. h BcT° rhythm was pathological in six out of ten cases. Post-surgery sleep efficiency normalized in four out of eight patients, whereas nine out of ten patients presented with two to six longer daytime naps. Diurnal naps were mainly present in patients showing pre-operative involvement of the third ventricle floor. 24. h BcT° remained pathological in only one out of six cases, returned to normal in two and improved in three. 24. h BcT° rhythm improved more in papillary CPs than in adamantomatous CPs. Our data confirmed that both CP and surgery frequently disrupt the sleep-wake cycle and BcT° rhythms. Tumour location and histotype may be related to a worse postsurgical outcome. Therefore, in-depth investigation including circadian monitoring is crucial for surgical outcome.
